<p>I actually really don’t think too much about #1 - although I know my friends that take the hard science courses worry about them more than I do. As far as coursework, it varies depending on what classes you take. I’ve always had time for leisure activities and procrastination, but some classes had larger loads than others and the work could add up.
And as far as scheduling goes, don’t give up when you don’t get into a class you want. When I didn’t get into two classes I wanted for next semester, I just kept checking online until spots opened up, and now I’m in both.</p>
